Design and Operation of a Rotatable Valve Cam to Improve the Efficiency of a Hydraulic Motor in an Inline Hydro-Mechanical Transmission
… (HMTs) split transmitted power between hydraulic and mechanical channels, which allows them to maintain continuously variable transmission ratios while achieving higher efficiency than hydrostatic transmissions. The Hondamatic inline HMT (iHMT) reduces the size, cost, and complexity …

Analysis of hydraulic power transduction in regenerative rotary shock absorbers as function of working fluid kinematic viscosity
… to the effective power transduction seen by a hydraulic motor. Applications of this research specifically relate to energy recovery from a vehicle suspension system through the shock absorbers. A regenerative, hydraulic-based, rotary shock absorber was designed and fabricated for the purposes …
